木文测定并研究了二个查尔酮三岔共轭系和一个苯多烯醛线型系,共十二个同系化合物。在50％对氧陆(?)、50％乙醇和50％二甲基甲酰胺的(0.1,kcl,0.1f醋酸和0.1f磷酸)缓冲溶液中的极谱。以还原半波电位ε1/2对相应的同系因子(1/α)2/N作图可得较好的线性关系,相关系数γ在0.90以上。实验结果表明,三岔共轭系的较短一枝分岔链只起代基的作用。讨论了溶剂极性的影响。 A total of twelve homologous compounds were identified and studied in two chalcone trifurfies and a benzophenone linear system. Polarography in 50% buffered solution of (0.1, kcl, 0.1f acetic acid and 0.1f phosphoric acid) buffer solution of oxygen (?), 50% ethanol and 50% dimethylformamide. The best half-wave potential ε1 / 2 for the corresponding homologous factors (1 / α) 2 / N mapping good linear relationship, the correlation coefficient γ of 0.90 or more. The experimental results show that the shorter branching chains of the trifurcated conjugate only act as substituents. The effect of solvent polarity is discussed.
